Or are you thinking of `sqrt_approx` - deprecated since http://trac.sagemath.org/sage_trac/ticket/4611 ?

I found online an old (ver 1.4.1) sage manual that says that square_root() for rationals: "Return the positive rational square root of self, or raises a ValueError if self is not a perfect square."

So with this information is easy enough to code up a simple function to replace it.

I do wonder why it went away and or if it has been renamed or replaced somehow.
